But that doesn’t mean that there’s absolutely nothing to help you learn the fundamentals of project development with React. You can find plenty of material on how to get started with React project development. There are numerous online articles that teach the core steps of app development, along with the source code. 

As a beginner, the task of developing React projects from scratch may seem challenging, but there’s a secret to simplifying the process – break down an application into smaller components. Try to focus on building one feature at a time, and keep connecting the dots as you go. As you continue to practice and experiment with different React tools and ecosystems, you will understand the common patterns of app development and also which tools are best for developing specific features of a React app. 

Additional tip: Often, beginners harbor the misconception that they must build an app’s backend from the ground up, but it’s not necessary. You can simply leverage serverless technologies such as AWS Amplify, Firebase, and Hasura to equip your app with an out-of-the-box backend. These tools not only save your time but also help amplify your productivity.

What is React?

React is a User Interface development library based on JavaScript. It is managed by Facebook and also an open-source development community. Although React is more of a library than a language and is frequently used to make web development. React started in May 2013 and has since grown to become one of the most widely used frontend frameworks for website development. Compared to JavaScript, where code can rapidly become difficult, React makes things simpler for constructing dynamic web applications since it takes less coding and provides more outstanding features. React makes use of the Virtual DOM to speed up the development of web apps as instead of updating all of the elements repeatedly, Virtual DOM examines an element's previous states and updates just the objects in the Real DOM that have changed.

What are the disadvantages of using React?

In the case of a disadvantage, because the React environment is constantly changing, some developers are hesitant to relearn new methods of doing things on a frequent basis. React technologies don't have proper documentation as they are evolving and developing at such a rapid pace that there is no time actually to define and document them properly. React solely covers the app's UI Layers and nothing else, so other applications are required along with it to develop an application. React takes advantage of JSX, a syntactic extension that is regarded as a barrier by many individuals of the developer community that allows HTML and JavaScript to coexist. Developers grumble about the learning curve's intricacy.

What are the real-life use cases of React?

React is widely utilized in Facebook's codebase, which comprises over 20,000 components. React is used not just on the web version of Facebook, but it also serves as the foundation for other Facebook products such as Whatsapp and Instagram. Instagram's online version is built entirely with the React framework. React allows for a number of excellent features in the online version of Instagram. Engineers at the well-known Khan Academy are utilizing all of the fantastic capabilities of both React components and React Native, a mobile app development framework. The React version also works with Netflix, particularly on its Gibbon platform, which replaces the DOM in web browsers for low-cost TV sets.
